Etymology of hologram
The word 'hologram' was coined in the 1940s by Hungarian-British physicist Dennis Gabor, who was awarded the Nobel Prize in Physics in 1971 for his invention of holography. The term is derived from the Greek words 'holos' (whole) and 'gramma' (message), reflecting the three-dimensional nature of the image.
